Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.04566 | $0.04566 |
| Opus 5 | $0.02283 | $0.02283 |
| Sonnet 5 | $0.00913 | $0.00913 |
| Haiku 4.5 | $0.00457 | $0.00457 |
Grade A, and why
JumpStart-AutoNav AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 314 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Jump Start Framework -- Agent Instructions
System Notice: This repository is managed by the Jump Start spec-driven framework. All AI agents operating in this context must adhere strictly to the protocols defined below.
Workflow Overview
The development lifecycle follows strict, sequential phases. No phase may begin until the previous phase's artifact is explicitly approved by the human operator. For brownfield projects, a pre-phase Scout agent analyzes the existing codebase before Phase 0 begins.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

JumpStart-AutoNav AGENTS.md is an instructions file published in the GitHub repository CGSOG-JumpStarts/JumpStart-AutoNav (10 stars, last pushed 4mo ago), licensed MIT. It adds 4,566 tokens to every session, about $0.0228 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
